Need advice—X5 M purchase this week

[Sandbag]

I live in a state that has no BMW dealers. I found the car I want online on a dealer website. The dealer is a 450 mile drive from where I am. I called them put a hold on the car. Later this week I will go there to experience the vehicle and purchase it.

Here is some information on the car. Sorry about the all-CAPs below. I cut and pasted it from the web page.

2012 BMW X5 M

ACTIVE VENTILATED SEAT PKG
BAMBOO BEIGE PERFORATED MERINO LEATHER SEAT TRIM
BMW APPS
CARBON LEATHER TRIM
COLD WEATHER PKG
COMFORT ACCESS KEYLESS ENTRY
DRIVER ASSISTANCE PKG
LEATHER DASHBOARD & CENTER CONSOLE
MONTE CARLO BLUE METALLIC
PREMIUM SOUND PKG
REAR CLIMATE PKG
SOFT-CLOSE AUTOMATIC DOORS

The list price for this configuration is $99,125, I will be adding window tinting to the driver's side and passenger's side windows, along with the Clear Bra to the front end of the car. They will install a towing package. I also will be getting a spare tire, jack, and related stuff for flat tires (I will be taking the run-flats off in wintertime to have Blizzaks or X-Ice tires on the vehicle).

My questions for you:

1. I would appreciate any tips you may have on negotiating a good price with the dealer and what you think I can get this car for.

TrueCar.com shows a dealer cost of $90,005, a factory invoice of $92,290, an average price of $98,116, and the sticker price of $99,825 (which includes Destination Fee). These amounts do not include the add-ons to the list in the previous paragraph.

TrueCar.com says:
"For the base model, the average price for a new 2012 BMW X5 M is trending $2,442 below the manufacturer's sticker price. For the one available 2012 BMW X5 M trim line, the average savings is 2.798% below the sticker price."

"The 2012 BMW X5 M has a TrueCar Price Flexibility Score of 81, which indicates that new car buyers have the potential to negotiate a price significantly below the average price paid. Unfortunately, because the flexibility is high, it also means that many car dealerships are selling the BMW X5 M above the average price paid."

2. This is my first BMW, and what a glorious machine this is, so I don't know how long I will have it. Any ideas on the advisability of extending the Maintenance Program Upgrade and the Extended Vehicle Protection?

I know maintenance from the dealers is not cheap, but I don't if extending the Maintenance Program Upgrade will save money for me. What experiences have you had with this and the Extended Vehicle Protection plan. I did find out that if you sell the car while the car in in the Extended Vehicle Protection time, you can get a prorated refund or transfer it to the new buyer. The Maintenance Program Upgrade is transferable, but there is no refund available.


3. When you need a windshield replaced, do you get it done at the BMW dealer or have you entrusted your baby to local glass repair places? I'm asking, because once I have the car at my home base, the closest dealer is 200 miles away.

Thanks in advance for any input and thoughts you will have for my situation.
